Sewage treatment is a technical job, and if you don't do it well, the effluent COD or BOD will give you a "surprise". But don't worry, I've got a couple of tricks to help you with this.
Equipment inspection and cleaning
Aging or clogged equipment can lead to a compromise in the treatment effect. Therefore, it is necessary to have a "spa" and "physical examination" of the equipment regularly.
Adjust the process
Sometimes, a change of treatment or a little adjustment of process parameters can solve a big problem. It's like stir-frying, the heat is important.
Increase aeration
Increasing the oxygen in sewage** is like adding firewood to microorganisms to make them more energetic in breaking down COD and BOD.
Extend the aeration time
Give microorganisms more time to react and improve treatment efficiency. It's like letting the stir-fry simmer for a while longer, making it more flavorful.
Pay attention to the quality of the incoming water
If the quality of the influent water changes, the treatment effect will also change. Therefore, we should always pay attention to changes in water quality and respond in a timely manner.
Optimize sludge treatment
Improper sludge disposal can lead to problems backlash. Therefore, reasonable sludge treatment is also a key part.
Strengthen surveillance
Identify and solve problems in a timely manner, adjust process parameters, and ensure the stability and efficiency of the treatment process. It's like playing a game, you have to keep an eye on the progress of the game and adjust your strategy in time.
Seek technical support
If you can't figure it out on your own, you might as well ask an expert for advice. After all, there must be my teacher in a threesome.
